With the acquisition of Fox studios by Disney, the Marvel Universe will finally be able to showcase alongside their heroes the X-men! Prior to the merger however, Fox had announced that their next upcoming X-men movie would revolve around the story of the “Dark Phoenix.”
The Dark Phoenix storyline was originally presented in the Uncanny X-men comics with issue #134 being her 1st appearance. As that comic is somewhat pricey, Hicollector is suggesting you pickup the reprint of that comic – Classic X-men #40. This comic was released in November 1989 and is still reasonably priced.
As Classic X-men #40 is a copper age comic, Hicollector recommends you pick it up at a 9.0 or higher.
